The Centrifugal Sifter For Our Flour is a product for finely grading, removing impurities, and screening flour. It uses centrifugal force to rapidly disperse and sieve the material within the sieve drum, ensuring a uniform particle size in the finished flour. It effectively removes impurities (such as fibers, tiny insect eggs, and lumps) from the flour and ensures a uniform powder particle size. When selecting equipment, the screen mesh size (typically 80 to 120 mesh) must be precisely matched to process requirements to control powder fineness, and the model should be determined based on production capacity. For throughput rates up to 800 kilograms per hour (kg/h), this equipment is perfectly integrated into continuous production lines. It operates stably in a fully enclosed, dust-free environment and features self-cleaning and anti-clogging features, making it an ideal choice for improving the quality of high-end flour.
Flour needs to be sieved through 80 to 800 mesh (pore sizes range from approximately 180μm to 18μm). For high-precision sieving, a centrifugal sieve is recommended. To achieve high precision and prevent clogging, choose a high-quality stainless steel mesh or special wire mesh. For extremely fine mesh sizes, the sieve frame must have sufficient tension and strength to prevent deformation under centrifugal force. Ideally, the equipment should feature a quick screen change function to accommodate production needs of varying mesh sizes.
The motor power of the Centrifugal Sifter for Our Flour must be matched to the mesh size and throughput. Higher mesh sizes increase sieving resistance, requiring stronger centrifugal force to force the material through and simultaneously clean the mesh. A variable frequency motor is preferred, offering flexible spindle speed adjustment for precise control of centrifugal force to accommodate sieving from coarse to fine mesh sizes.
The equipment supplier should clearly provide your mesh size requirements (e.g., 100 or 200 mesh for key screening) and the corresponding target hourly throughput (e.g., 800 kg/h). A high mesh count significantly reduces the flour removal rate. Suppliers should recommend appropriate machine dimensions based on your specific specifications (such as sieve drum diameter).
The Centrifugal Sifter for Our Flour uses internal, high-speed rotating brushes or scrapers to generate strong centrifugal force on the material, forcing flour particles through the sieve. This positive mechanical force ensures a high throughput rate even for fine, easily clogged sieves. The flour is processed in a completely enclosed environment, completely eliminating dust. While sieving, the rotating brushes or scrapers continuously clean the sieve surface, effectively breaking up soft agglomerates and preventing clogging.
In terms of screening accuracy, the Centrifugal Sifter can be configured with different sieves according to user needs. Common mesh sizes range from 60 to 500 mesh, effectively meeting diverse requirements for coarse screening, fine screening, and impurity removal. This device maintains consistent grading accuracy for common flour fineness control requirements, such as 80-mesh, 120-mesh, and 200-mesh screens, ensuring the purity of both the upper and lower fractions. The standard model boasts a throughput of 500 kg to 5 tons per hour, depending on the screen diameter, mesh size, and material characteristics. Even in large-scale flour processing lines, a single unit can operate continuously and stably, and can be integrated with automatic loading and unloading systems for unmanned operation.
The Centrifugal Sifter For Our Flour is not limited to standard wheat flour; it is also suitable for sieving high-gluten flour, low-gluten flour, whole wheat flour, and specialty functional flours. Its unique enclosed design effectively prevents dust leakage, meets food-grade safety standards, and ensures cleanliness and operator safety. During the sieving process, the device features an automatic screen cleaning device, reducing the risk of screen blockage and downtime, significantly improving operational continuity. For flour manufacturers, the rational selection and configuration of screens with different mesh sizes can not only achieve production line flexibility, but also ensure the stability of the end product in terms of fineness and purity.
